Although it is close to the \u003cem\u003eInvestigations\u003c\/em\u003e in some points, and to the \u003cem\u003ePhilosophische Bemerkungen\u003c\/em\u003e at others, the \u003cem\u003ePhilosophical Grammar\u003c\/em\u003e is an independent work which covers new ground.\u003c\/p\u003e\n\n\u003cp\u003eIt is Wittgenstein's fullest treatment of logic and mathematics in their connection with his later understanding of 'proposition', 'sign', and 'system'. He also discusses inference and generality — criticising views of Frege and Russell as well as earlier views of his own — and the treatment of mathematical proof in this book, especially of inductive or recursive proofs, is deeper and more extensive than previously.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Unknown","offers":[{"title":"Default Title","offer_id":47461245681900,"sku":"9780631118916","price":78.99,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0705\/7784\/8556\/files\/9780631118916-philosophical-grammar.jpg?v=1774963557","url":"https:\/\/bookhero.co.nz\/products\/philosophical-grammar-by-ludwig-wittgenstein-9780631118916","provider":"Book Hero","version":"1.0","type":"link"}
